Windows 10: cannot open people app

When try to open Windows 10 People, blank blue screen (w/ people synbol in middle) comes up for a second, then screen goes to Mail. Mail seems to work fine and calendar opens OK (although I don't use it).
Had a problem recently when HP110 computer wouldn't come out of sleep. After several tries said it was restoring to previous settings before problem occurred. Haven't been able to open people since, and would like to add some addresses.
While I'm on the subject, Many of the contacts I had under windows 8 were not in the windows 10 People (although most were). And they didn't seem to automatically be added when I sent or received something, the way they used to be (may be a settings issue).
Thx for any help and guidance.

Not sure why you are experiencing that issue CeeDee.

Did you try powering off (so you see the goodbye message) then powering back on?

Have you checked for updates on your device?

 

nobody has responded with anything. Does anybody have any idea how to solve this problem? I'm about to dump Windows 10 altogether and tell everybody I know it sucks...certainly hasn't been working for me.
